Density Calculation Method Of Polyurethane Prepolymer
Nov 02, 2021
With the increasing demand and types of polyurethane prepolymers in my country, the output of polyurethane prepolymers has increased rapidly. The more knowledge we understand when using, the more advantageous it is. Then how to calculate the density of polyurethane prepolymers What about?
Utensils: a 100ml or 250ml graduated cylinder, a weighing range of 500g balance (accuracy ±0.5g), a calculator, and a funnel.
Process: Pour the polyurethane prepolymer into the measuring cylinder evenly, and add to the 100ml mark. The plane after adding should be level with the 100ml mark, then pour the polyurethane prepolymer in the measuring cylinder into the balance and weigh it to get the value M . The calculation formula of bulk density is: ρ (density) = M (mass)/V (volume), the unit of this calculation is: grams/cubic centimeter, if you need to convert to kilograms/cubic meter, multiply by 1000.
